Defects of the POSIX Sporadic Server and How to Correct Them
Mark J. Stanovich, Theodore P. Baker, An-I Wang, Michael González Harbour · 2010
The specification of the sporadic server real-time scheduling policy in the IEEE POSIX standard is defective, and needs to be corrected. Via experiments using a POSIX sporadic server implementation under Linux, as well as simulations, we have shown and confirmed previously unreported defects. We propose and demonstrate a corrected sporadic server formulation that eliminates these defects without changes to the syntax of the API or any significant increase in implementation complexity.
